> Needles to say, I can't get the drives attention once it is hooked up.

> Can't get the CD's attention when it is hooked up either.
> The only really unusual thing hooked up to the machine is a SolFlower

  I ended up putting 2 reply's together and came up with a possible
  answer. Someone said that if the 1.3 Gig disk worked okay at the
  end of the SCSI chain to put it back at the end of the SCSI chain.
  Someone else mentioned that it sounded like one of my SCSI devices
  was internally terminated and causing problems when put in the
  middle of the SCSI chain.

  Well it turns out that the problems do go away when the 1.3 Gig disk
  is at the end of the SCSI chain. I will check later when I have the
  time to try and verify that the 1.3 Gig disk is internally terminated.
  Although my guess is that it is internally terminated. It is very
  touchy about which SCSI port is SCSI in and which one is SCSI out.

  Thanks again,
